Determination of the Permeability of Paramagnetic Materials

The magnetic permeability µ characterises the permeability or magnetic conductivity of materials. It is the product of the magnetic field strength µ0 und the relative permeability µr, which we can determine for paramagnetic materials (µr = 1...2).
The relative permeability of vacuum is 1.
Materials can be classified into 3 groups with regard to their relative permeability:

  • Diamagnetic materials     0 ≤ µr < 1
  • Paramagnetic materials     µr > 1
  • Ferromagnetic materials     µr >> 1

The flux-gate magnetometer covers the measuring range from µr = 1.001 to 1.999. The results are displayed with a resolution of 0.001. The measurements can be executed at our place or on-site at your premises.
